On the Braves-Giants Marathon Game

Mark O'Neill, writing for Around the Foghorn:

On July 2, 1963, one of the greatest pitching duels in major league history took place at Candlestick Park, when 25-year-old Juan Marichal, of the San Francisco Giants, out-dueled 42-year-old Warren Spahn of the Milwaukee Braves, 1-0, in a marathon sixteen-inning game. The contest was ultimately won by the Giants when Willie Mays hit a solo home run in the bottom of the sixteenth.
In an era of pitch-counts and specialization of bullpen personnel, it is inconceivable that any pitcher today would ever engage in this kind of lengthy appearance, but back in the day such was not the case. Complete games were the norm and guys prided themselves on their durability. But 227 pitches worth of durability? That’s the number of pitches that Marichal is said to have thrown on that momentous night. When it was suggested that he leave the game, Marichal’s response was something to the effect that as long as that old geezer (Spahn) was still out there, he wasn’t going anywhere. Here's the box score for the game. Not only is Marichal's 227 pitches thrown incredible --- a Herculean feat by today's standards --- but consider too that Spahn was 42 years old when he pitched in this game. That's right: a 42-year-old veteran, long past his prime, pitched 16 innings, himself hurling 201 pitches. Amazing.
